Indoor Air Quality in San Luis Obispo: what's different
Indoor Air Quality work in San Luis Obispo follows the local climate. Seasonal swings mean both humid summers and dry winters. Duct leakage, filtration and humidity control all affect comfort and bills.
Many older homes have gas forced-air furnaces or wall heaters and no central AC, relying on the marine climate. Student rentals often have older equipment, and newer homes are built all-electric with heat pumps.
The indoor air quality services San Luis Obispo homeowners ask for most are fresh-Air Ventilation (ERV/HRV). Balanced ventilation for tight newer homes.
The City of San Luis Obispo Community Development Department issues mechanical permits and encourages all-electric equipment, and California requires C-20 licensed contractors and Title 24 compliance.
